I love Gelaskins and have skinned my iPod Classic, iPhone 3GS as well as my Dell XPS laptop. I get compliments on the skins all the time and asked where to get them. These skins are durable - all of my skins look as good as they day I bough them!
I prefer to browse their full selection on their website but I'll pop down to the kiosk at the Eaton Centre so that I don't have to pay their ridiculous shipping prices.
When I ordered my laptop and iPod skins a couple of years ago the kiosk didn't exist and the only shipping method that they use is UPS - which is expensive ($14.95, almost the price of one of their skins!) and annoying because if I'm not home to receive the package it ends up who knows where! I also wasn't pleased that they charged everything in US dollars on the website, but it's a Toronto based company. I'm so happy that there is a physical location I can shop from now.
I had to trim down my 15" laptop skin a bit, but luckily I have a paper slicer and a corner nipping tool that I bought for scrapbooking so I was able to round off the corners nicely. The skins apply very easily and leave absolutely no residue when removed. They are very forgiving so if you don't put it on straight you can easily remove it and reposition.
I love that you can download a matching wallpaper off their website.
When I purchased my iPhone skin at the kiosk I also picked up a screen protector (GelaScreens) since it was there. I should have done my homework first because I wasted $10 on it. Their skins are fabulous, but their screen protectors are NOT! They made the screen smudgy and created more fingerprints than just the bare glass on the phone. Luckily the GelaScreen protector removed as easily as the skins and I was able to throw it out and buy a better product at the Apple Store.
I would give GelaSkins 5 stars, but their awful GelaScreens product and their ridiculous online shipping prices knocks one off.
